relay or solenoid?
Thanks, Boss.The EEC Relay
Inertia switch and fuel pump wiring: Codes 87, 95 and 96.
These codes relate to low or no power reaching the fuel pump. Start testing at the fuel pump relay. The relay must respond to the EEC processor and the relay contacts must be a low resistance path for fuel pump power. Relay testing can be done in a couple minutes with the fuel pump test table.
Fuel pump relay testing
1. Use solenoid test at EEC pin 22 to check relay coil current draw.
2. Voltage at pump power terminal must be within .5v of battery power when relay is turned on with amp meter at pin 22. Check power from battery if voltage is low. Check the inertia switch and fuse if battery voltage is missing.
Pin 22- (light blue-orange) Grounded to turn "on". Voltage will drop to about 1v when "on". Current draw will be 160 to 270mA
Pin 8- fuel pump monitor (dark green-yellow) 0v engine off, battery voltage with engine running.
